What is the minimum speed the bucket can travel so no water spills out?
You are rotating a bucket of water in a vertical circle. The radius of rotation is 0.95m, what is the minimum speed the bucket can travel so no water spills out?

Centripetal force must equal weight
mV²/r = mg
V² = rg = 0.98•9.8
V = 3.05 m/s
Centripetal force f = mV²/r = mrω²
ω is angular velocity in radians/sec
1 radian/sec = 9.55 rev/min
m is mass in kg
r is radius of circle in meters
V is the tangental velocity in m/s = ωr
f is in Newtons
